Abstract:

Abstract 10.1002/zoo.20071.abs The suckling behavior of three bottlenose dolphin (Tursiops truncatus) mother–calf pairs at the Kolmården Wild Animal Park, Sweden, was followed from birth until the calves were 1 year old, with emphasis on the behavior of the mothers toward other dolphins present in pool. The results show that 80.44% of the sucklings occurred when the dams were not accompanied by another member of the group. This preference declined, as the calf grew older, for all three dams. Three factors influenced this company preference in relation to nursing and contributed to the total variance in a detectable way: the month post partum, company preference, and the mother’s ID, i.e., which mother was involved. The time between the category “dam leaves company” and the beginning of nursing increased over the months for all three dams. These results indicate that another dolphin is not automatically an asset to a dam with a newborn, and that, in human care, ample space and limited number of pool mates must be provided to allow the dam the necessary privacy in connection with nursing.
